Abstract
A method is provided to compress and display received data from a toroidal olume search sonar (TVSS) in terms of horizontal range. For any TVSS receive beam having a horizontal component projection that is equal to or greater than a selected horizontal range, the data values occurring at that selected horizontal range are averaged to form a compressed data value. Range dependent weight factors are applied during the averaging process so that the effects of surface and bottom reverberation do not bias the compressed data value. The compressed data value can then be displayed as a function of horizontal range for a series of sonar pings in order to provide a time history.
